A reincarnation of Oda Nobunaga, a Japanese daimyō who attempted to unify Japan during the late Sengoku period. He came back in the 21st century as a Shiba Inu.

The Warring States Period is a time of feuding warlords. Oda Nobunaga, the greatest of them all, is reborn in modern-day Japan... as a shiba-inu! The other generals of the era, too, have also inexplicably been reborn as dogs. Their warring states rivalry will resume at the dog park!<br><br>(Source: Crunchyroll)

In the "one-of-a-kind samurai-general-reincarnated-as-a-canine comedy," Nobunaga perishes at Honnouji as in history, and reincarnates in modern-day Japan as a dog named Shinamon. Other Warring States era warlords such as Takeda Shingen eventually join him, also as dogs.
